Tropical Travel Trouble 010 Fever, Arthralgia and Rash

LITFL • Life in the Fast Lane Medical Blog LITFL • Life in the Fast Lane Medical Blog - Emergency medicine and critical care medical education blog aka Tropical Travel Trouble 010 Peer Reviewer: Dr Jennifer Ho, ID physician QLD, Australia You are an ED doc working in Perth over schoolies week. An 18 yo man comes into ED complaining of fever, rash a “cracking headache” and body aches. He has just hopped off the plane from Bali where he spent the last 2 weeks partying, boozing and running amok. He got bitten by “loads” of mosquitoes because he forgot to take insect repellent. On examination he looks miserable, temp 39.8 °C, HR 115, BP 108/60, blanching maculopapular rash over his face, thorax, and flexor surfaces. Questions: Q1. What could this be? Answer and interpretation expand(document.getElementById('ddet1986166261'));expand(document.getElementById('ddetlink1986166261')) Acute febrile illness in the returned traveller can be a number of diagnoses (not exhaustive): Bacterial: strep throat, leptospirosis, toxic shock syndrome, rickettsia, typhoid, Melioidosis and meningitis. Viral: Fifth disease, enterovirus, scarlet fever, hepatitis, zika, Chikungunya, Roseola, EBV, HIV seroconversion, West Nile virus, influenza, adenovirus, measles and Rubella. Parasitic: malaria Non infectious: ITP, Acute leukaemia, drug reaction and Kawasaki in the young. Due to fact this is a tropical post the most likely culprit is an arbovirus (an...

ConclusionFDG-PET/CT may steer the diagnosis (particularly thanks to a relatively high PPV and value of semiquantitative measurements), but cannot always classify vertebral bone lesions as malignant or benign with sufficient certainty. In these cases, biopsy and/or follow-up remain necessary to establish a final diagnosis.

ConclusionWe achieved promising results with this computer-aided diagnosis method that we tried to develop using convolutional neural networks based on transfer learning. This method can help clinicians for the diagnosis of hip osteoarthritis while interpreting plain pelvic radiographs, also provides assistance for a second objective interpretation. It may also reduce the need for advanced imaging methods in the diagnosis of hip osteoarthritis.

AbstractThe biceps brachii myotendinous unit, particularly the long head of the biceps tendon and its labral attachment, is a common cause of shoulder and arm pain. Its complex anatomy and normal variations can present a challenge when interpreting MR images. The purpose of this manuscript is to review the proximal biceps anatomy, variants, pathology, and post-operative appearance as seen on MRI. Recent data regarding the accuracy of clinical examination and MRI will be summarized.

AbstractCalcific tendinopathy typically affects the shoulder rotator cuff tendons. Its management includes shock wave therapy and US-guided percutaneous irrigation, with surgery being less and less used. Extra-shoulder calcific tendinopathy is relatively infrequent and typically affects the hip. While the diagnostic techniques and the treatment options for shoulder calcific tendinopathy have been extensively described, there are only anecdotic reports on the other sites. In this paper, we have reported an unusual case of non-insertional Achilles calcific tendinopathy which occurred many years after Achilles surgical repair...

ConclusionWe report statistically significant differences in the T1 ρ value in the superficial and middle zones of the lateral patella in patients with patellofemoral pain syndrome who had no abnormalities seen on conventional MRI sequences, suggesting an alteration the macromolecular structure of the cartilage in this population.

We report a case of a 55-year-old patient being resuscitated emergently with proximal humeral intraosseous infusion for cardiac and respiratory arrest secondary to status epilepticus. After successful resuscitation and removal of the intraosseous cannula, the patient noted new-onset shoulder pain. The patient was ultimately diagnosed with an iatrogenic fracture of the anatomic neck of the humerus through the intraosseous needle tract when the appropriate history was obtained in conjunction with cross-sectional imaging. As the use of intraosseous access expands, such fractures may well be seen more frequently. Intraosseous ...

AbstractA 37-year-old man presented with a 2-year history of left hip pain. Pretherapeutic imaging demonstrated a 4  cm osteoblastoma located in the intertrochanteric region of the proximal femur, surrounded by extensive bone marrow edema. After multidisciplinary meeting, percutaneous cryoablation was decided and performed under computed tomography guidance using three cryoprobes to match the exact size and shap e of the tumor, resulting in complete resolution of symptoms. Magnetic resonance imaging follow-up demonstrated resolution of the bone marrow edema pattern and ingrowth of fat at the periphery of the ablation ...
